Abstract
The invention discloses a single base adjusting valve sealing structure which comprises a valve body, a valve base, a valve core, a valve cover and a packing pressing cover, wherein the valve base and the valve core are mounted inside the valve body; the valve cover is fixedly connected to the upper end of the valve body through a bolt; the valve rod is fixedly connected to the upper end of the valve core; the valve rod penetrates outside the valve cover upwards vertically; a partitioning ring, packing and the packing pressing cover are sequentially embedded between the valve cover and the valve rod; a packing gasket is embedded between the packing pressing cover and the packing; an elastic sealing ring is embedded between the packing pressing cover and the valve cover; outer threads are formed in the upper end of the valve cover; a locking screw nut is in threaded connection with the position of the outer threads formed in the upper end of the valve cover. As the locking screw nut is in threaded connection with the position of the outer threads formed in the upper end of the valve cover, the elastic sealing ring is embedded between the valve cover and the packing pressing cover, and the packing gasket is embedded between the packing pressing cover and the packing, so that the adjusting valve leakage is avoided, the sealing property of the adjusting valve is improved, the processing and assembling difficulty is alleviated, and the production efficiency is improved.
Description
technical field:
The present invention relates to modulating valve and manufacture field, particularly a kind of single-seat adjusting valve sealing configuration.
background technique:
Modulating valve is for regulating the flow of medium, pressure and liquid level.According to regulator site signal, the aperture of autocontrol valve, thus the adjustment reaching rate-of flow, pressure and liquid level.Regulator apply valve, in use will in the face of the problem that how to prevent medium from leaking outside in media such as air, water, steam, various Korrosionsmedium, mud, oil products, especially to inflammable, explosive,
The medium of easy generation radiation must ensure zero leakage.
In prior art, the Gland of modulating valve is by processing screw hole on axial end on Gland and valve gap, the mode screwing in clamping bolt in screw is fixed, machining accuracy is higher, and both sides clamping bolt screw-in depth inequality causes Gland upward pressure inequality easily to make Gland tilt, affect sealing effect, easily cause and leak.
summary of the invention:
The invention provides a kind of single-seat adjusting valve sealing configuration, solve requirement on machining accuracy in above-mentioned prior art high, sealing effect is bad, the problem easily leaked.
Technology solution of the present invention is as follows: a kind of single-seat adjusting valve sealing configuration, it includes valve body, valve seat, spool, valve gap, Gland, valve seat and spool are installed in described valve body, described valve body upper end has been bolted to connection valve gap, described spool upper end is fixedly connected with valve rod, described valve rod wears out valve gap straight up, spacer ring is embedded with successively from top to bottom between described valve gap and valve rod, filler and Gland, filler pad is embedded with between described Gland and filler, elastic seal ring is embedded with between described Gland and valve gap, described valve gap upper end forms outside thread, described valve gap upper end forms outside thread position and is bolted with locking nut.
Further, be provided with guide element between described valve body upper end and spool, described guide element matches with valve body and spool, and described guide element upper and lower end and valve gap, valve body touching position are embedded with spiral wound gasket respectively.Ensure to realize sealing between guide element and valve gap, valve body contact face.
Further, spiral wound gasket is embedded with between described valve body and valve seat.Ensure to realize sealing between valve body and the contact surface of valve seat.
Further, described filler is reverse V-shaped filler.Reverse V-shaped filler can rely on V-structure to rely on oneself sealing, thus ensures the sealing of single-seat adjusting valve.
Beneficial effect of the present invention is: the seal form adopting the locking nut that to be spirally connected in valve gap upper end, by the form of fastening bolt axial restraint Gland in prior art, ensure Gland uniform force, reduce processing, assembling difficulty, and nested elastic seal ring between valve gap and Gland, buffering, to reduce between valve gap and Gland because of the deformation that radial stress may cause, ensure sealing simultaneously; Filler pad is embedded between Gland and filler, and guide element upper and lower end and valve gap, valve body touching position, and be embedded with spiral wound gasket respectively between valve body and valve seat, prevent modulating valve from leaking further, improve the sealability of modulating valve, improve quality of product and manufacturing efficiency.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention;
Fig. 2 is that Fig. 1 centre circle shows that A's sends out large figure.
In figure: 1, valve body; 2, valve seat; 3, spool; 4, valve gap; 5, Gland; 6, valve rod; 7, spacer ring; 8, filler; 9, filler pad; 10, elastic seal ring; 11, locking nut; 12, guide element; 13, spiral wound gasket.
